Question

我有以下代码将地址转换为纬度和经度，但只有在单输入中输入时才有效，但我有一个允许用户在不同行中输入地址，城市，州和国家的表单，任何人都可以告诉我如何转换并将给定地址保存到纬度和经度

 <?php
    ob_start();
    $con=mysqli_connect("localhost","root","","db");
    // Check connection
    if (mysqli_connect_errno())     
        {
            echo "Failed to connect to MySQL: " . mysqli_connect_error();
        }

    if($_POST)
        {
            $data_arr = geocode($_POST['address']); // get latitude, longitude and formatted address
            if($data_arr)// if able to geocode the address
                {
                    $latitude = $data_arr[0];
                    $longitude = $data_arr[1];
                    $formatted_address = $data_arr[2];
                }   
                $address = mysqli_real_escape_string($con, $_POST['address']);
                $sql="INSERT INTO register_office (co_address,latitude,longitude) VALUES ('$address', '$latitude', '$longitude')";
                if (!mysqli_query($con,$sql)) 
                    {
                        die('Error: ' . mysqli_error($con));
                    }
        }
    mysqli_close($con);     
    ?>

    <?php

Answer 1

您最好检查值是否为空...之后，使用逗号,连接它们，如下所示：

$addressFields = array(
    $_POST['addressline1'],
    $_POST['addressline2'],
    $_POST['addressline1'],
    $_POST['city'],
    $_POST['state'],
    $_POST['country'],    
);

$addressData = implode(', ', array_filter($addressFields));

在此代码段中，array_filter()用于过滤数组中的所有空字符串。 implode()使用逗号,作为＆＃39;胶水将字符串中的数组项连接在一起。然后，使用示例中的geocode()方法：

$data_arr = geocode($addressData);

Answer 2

将地址部分添加到一起形成一行，然后将其提交到Google Maps API。

$address_parts = array($addressline1, $addressline2, $addressline3, $city, $state, $country);
$address = implode(", ", $address_parts); // join the parts together divided by comma

Answer 3

听起来你应该能够将地址部分连接在一起，然后将其发送到？

E.g。

$address = $_POST['addressline1'] .','. $_POST['addressline2']  <<snip>> $_POST['country'];

$data_arr = geocode($address);

如果谷歌在重复逗号方面遇到问题，您可能需要构建一些if语句，以便只放入实际设置的位（此时构建数组并将其插入可能会更好）
